<p class=MsoNormal><font size=3 face="Times New Roman"><span style='font-size:
12.0pt'>I learned through a discussion with Chris Hill that there are four, and
possibly five types of servo lock for this VTR:<br>
1. Tone wheel lock<br>
2. Switch lock<br>
3. Pix lock<br>
4. Line lock <br>
And a possible #5. Whatever mode or combo of modes used in starting the tape
up. <br>
<br>
Another theory question is the explanation of the "outer loop" and
"inner loop" circuitry used in this machine for the servos. <br>
<br>
Thanks for any help you can give,<br>
